If you look on the leopard gecko forum, several people had this problem and said that putting a moist/humid hide on the floor with a heat source brought them out. Also said they have found them in warm places...refrig, water heater, etc. Hope this helps! Someone even said they found one after six months, still alive!-----2 Leos
